Where Did You Put Your ARB CKMTA12 (Air Compressor)?

Taking some inspiration from Alia's tank mount, I measured things and concluded both the ARB compressor and 4 liter tank will mount between the frame rails underneath the winch. Plenty of room there, length of wiring and plumbing runs are minimal and accesible. It is a little exposed, but no worse than many under tray mounts I've seen on trucks in Australia. A Harbor Freight winch mount plate will supply the basic mount. Should be able to do most of the assembly on the bench then lift into place for the final hookups.
 
I've got the discontinued OVS version of this same compressor .. but the mounting is the same. Started witih the Torfab bracket for the firewall but when I switched to dual batteries I had to remove it, as the compressor would bump into the newly relocated washer bottle. If anyone here can use this bracket, hit me up we can ship it to you. no really, you can have it.

I moved the compressor to the side of my ARB drawers. Drilled some holes in the trim kit panel and extended the switch wires, and a quick disconnet fitting for the air hose. So to use the compressor just hit the switch and plug in a hose.

Under the cover you can see the compressor just barely fits in there... it's a combination of resting up against the wheel well, and a few screws going in to the drawer.

The power is fed from a fuse panel on the other side of the drawers... 4ga + and - running from the 2nd battery. I'm not concerned with heat- it's usually cooler inside the truck than it is inside the engine. And I figure I can just pop off the cover plate of the drawers when I'm airing up. Only downside is any passenger not helping with airing up gets to listen to the air compressor and full volume.
 
It's really not that loud though. My wife hasn't complained and it's right under her seat.
 
One concern with the under winch mounting I am contemplatng, really any external mounting, is keeping excess crud out of the filters. Does anyone use a particular plastic snap lid that fits over the filters snugly (and which would be removed when using the compressor)?

Alternatively, I recall some reference to using a different air filter in place of the ARB-supplied ones. Anyone know what these might be?
 
I haven't tried but is it possible to remote mount, similar to how breathers for diffs are mounted?

People mount them behind the fender wells of jeeps. I think the biggest issue you will have is accidently running it during a water crossing for a locker engagement. And extra cost of occasional replacement of filters. It's not the best location but you'll probably be fine.

Both of mine are plumbed with nylon tubing and the filters remote mounted behind the primary battery

You can get a glympse of them in this video

Hmmm, that's an interesting location nakman. In my drawer system the fridge sits next to that location, so I use it to store items that I don't need often AS THE FRIDGE LIMITS ACCESSIBILTY! The air compressor would fall into that category, plus it's within the supplied wiring harnes length's a a 4 gauge cable going up front. After looking things over, keeping the compressor inside is probably for the best. My cubbyhole there already has a vent above it, because it used to house an inverter. The air tank will need to go between the LRA auxliary. tank and the inside of the rear bumoper, but there's room to add a second aur tank
